A written recipe tells one cook how to make something another has previously made. When that new cook executes a recipe, they follow instructions in order to achieve a desired output. These instructions reveal a way to get to B from A. Some cooks may not be comfortable proceeding without this clear direction. Others may feel that they cannot ignore the rules. But the design of the recipe assumes that cooks won’t deviate far from the proposed trajectory by training them to do as they are told.
